4. Coulomb's Law

Limitations of Coulomb’s Law

  1. Coulomb’s law is valid, if the average number of solvent molecules between the two interesting charge particles should be large.
  2. Coulomb’s law is valid, if the point charges are at rest.
  3. It is difficult to apply the Coulomb’s law when the charges are in arbitrary shape. Hence, we cannot determine the value of distance ‘d’ between the charges when they are in arbitrary shape.
